Product Description

The Speed box S was designed to provide rock solid performance and automatic Speed change functionality to your ac-powered turntable. You can now easily change between 33 and 45 RPM speeds with a push of a front-mounted button. The quartz-precision frequency regulation and integrated filter circuit give far better Speed stability for smooth and undisturbed motor operation. The small size of the Speed box S also allows you to place the unit on the same shelf as the turntable for easy access. It is compatible with all Pro-Ject turntables that use a 16v(ac) power supply (see list below for exclusions) and can even be used to play 78rpm records with the addition of an accessory pulley available for separate purchase. Compatibility: the Speed box S may not be used with Pro-Ject turntables with a built-in electronic Speed change, a DC power supply, an automatic switch-off, or an integrated phono preamp. (E.G.
